title: Preparation of environmental samples for determination of sulfonylurea herbicides by solid-phase extraction using a polymeric sorbent.
abstract: An analytical procedure was developed for rapid determination of sulfonylurea herbicides in water or soil. Samples were prepared by solid-phase extraction using polymeric sorbents in cartridges and analyzed by liquid chromatography with photodiode array detection. Recoveries were consistent for all sample matrixes tested and were generally > 85%, except for tribenuron methyl (75%). Detection limits were < 100 ng/L for water samples.
